Dimensional formula of joule
WebUsing dimension show that 1 joule =10 7 erg Medium Solution Verified by Toppr It is given that 1joule=10 7erg Both erg and joule are the units of energy in CGS and MKS respectively. The dimensional formula of energy is [ML 2T −2] Let 1joule=Xerg 1[M 1L 12T 1−2]=X[M 2L 22T 2−2] X= [M 2L 22T 2−2][M 1L 12T 1−2] X=[M 2M 1][L 2L 1]2[T 2T 1]2 WebThe dimensional formula would be [ M0 L1 T-1] Hence, we can conclude that the speed is dependent on only length and time, not mass. Dimensional equation. To get the dimensional equation, the physical quantity is equated with the dimensional formula. Example. Velocity = [ M0 L1 T-1] Here, velocity is the physical quantity, which is equated …

WebWhat is the formula of the Faraday Constant? This constant can be expressed in terms of two other physical constants as. F = eNA. Where, e is the charge of the electron in coulombs e = 1.60217662×10 -19 C. NA is the Avogadro constant. NA = … WebDimensional Formula of Joule. The dimensional formula of Joule is given by, [M 1 L 2 T-2] Where, M = Mass; L = Length; T = Time; Derivation. Joule is the SI unit of work done. Therefore, the dimensional formula of Joule is the same as that of the work done. …
WebThe heat energy can be determined by using the formula, Heat energy transferred= Q = m*c*ΔT Here, m = mass of the substance, c = specific heat and ΔT is the temperature difference Therefore, c = QmΔT Unit of heat is Joule = N m = Kg Ms-2 m The dimension of Q is [M1L2T-2] ΔT has dimension K, C = [M1L2T-2] / [M1] [K] = [L2T-2K-1] WebJoule : SI system, erg:CGS system Work = Force x Distance = Mass x Acceleration x Length = Mass x (Time) 2Length× Length Dimensions of work = [W]=[M 1L 2T −2] ∴a=1,b=2,c=−2. Now SI system CGS system M 1=1kg M 2=1kg L 1=1m L 2=1cm T 1=1s T 2=1s Here N 1=1,N 2=? ∴UsingN 2=N 1[M 2M 1]a[L 2L 1]b[T 2T 1]c =1[ …
